SURFACE GRINDING OR PLANlNG MACHINE.

SPECIFICATION forming part of Letters Patent No. 405,706, dated June 25, 1889.

Application filed March 22, 1888- Serial No. 268-160 -(No model.)

To [1 66 whom it may concern:

Be it known that I, ELWIN R. HYDE, a citizen of the United States of America, residing at Springfield, in the county of Hampden and State of Massachusetts, have invented new and useful Improvements in Surface Grinding or Planing Machines, of which the following is a specification.

This invention relates to improvements in machines for planing metal surfaces by grinding, operating in many respects similar to the well-kn own metal-planin g machines, in which a tool is used for removing the stock but the grinding means in the present class of machines consists of a rotatable grinding wheel or disk suitably supported and driven, the work to be operated upon thereby being placed upon and carried by a table or platen which, under suitable driving mechanism, is given a reciprocating motion in a horizontal plane upon its supporting and guiding bed and in proper relation to said grinding-wheel; and in the class of grinding-machines to which this invention particularly relates water is to be supplied to and upon the face of the grinding-wheel, or upon the face of the metal being ground thereby, for the purpose of preventing an expansion of the metal and consequent inaccuracy in the plane-surfacing; and the object of the present invention is, principally, to provide means for the conveyance of water to and upon the grindingwheel or the work being ground thereby, for then securing its disposition in the machine, whereby it will be confined and retained within desirable limits, and whereby any sediment or grit will be eliminated there from, and for then reeonveying same to the Work, and otherwise to increase the efficiency of machines of this class; and to these ends the invention consists in the constructions and combinations of parts, all substantially as will hereinafter more fully appear, and be set forth in the claims.

In the accompanying drawings the present invention is illustrated, and similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a perspective View of the surface grinding or planing machine. Fig 2 is a cross-section thereof on line 2 2, Fig. 1. Figs. 3 and 4 are respectively a front view and a sectional view of details to he hereinafter described. Fig. 5 is a perspective view of the reciprocating table for supporting and carrying the work. Figs. 0 and 7 .are longitudinal sectional views of Fig. 5 on the lines 6 6 and 7 7 thereof, respectively. Fig. 8 is a plan view of one of the water-receiving pans located in the bed under the table, and Fig. 9 is a section thereof on line 9 9. Fig. 10 is a view illustrative of the apparatus for purifying the water used with the machine and for reconveying such purified water to the grind ing'wheel. v

I11 the drawings, A represents the stationary bed of the machine supported on the standards I3, and carrying at one end por tion the uprights C, on which is guided the horizontal slide-bar D, and adapted for a vertical ad justinent by the engagement therewith of the screw-threaded shaf s E, operated through the gearing a b on the turning of the shaft F. Mounted upon the said slide-bar D is the sliding block G, with which the screw threaded shaft H engages for a cross-feed of said block, said shaft l-I being intermittently rotated under the action of the mechanism interposed between it and the driving-shaft.

J represents the table, having on its under side the longitudinally-extending V-ribs d, guided in the V-waysf of the bed, said table being provided with the longitudinally-extending rack K, into which meshes the gear-wheel L, mounted in suitable bearing-boxes g of the bed, and driven, through intermediate gearing, by the main shaft M, and all these mentioned parts being generally, in their construction and combination with each other, all as usual and common in metal-planin g machines, except as hereinafter particularly set forth.

The bed A at its upper part and each side of its side walls h is provided for its whole length with longitudinally-extending shallow trough-shaped wings or gutters 12, closed at their ends, and inside of said side Walls h of the bed the same is provided with oppositelydisposed longitudinal shelves 13, upon which is placed a removable metal pan 14:, of alength substantially that of the bed, or otherwise, as desired. The pan 14 at its middle portion is provided with an aperture 15, surroundedjory a Wall or lip 16, as seen in Figs. 2, 8, and 9, through which aperture the periphery of the gear L is passed to mesh with the rack K 'of the table, the provision of the surrounding lip serving to retain the holding capability of the pan and to guard the escape or splashing of water therefrom upon and about the said gear.

The table J isprovided with the usual T- groove Z in one edge for the support and guiding of the adjustable shipping-dogs m, and is, for the greater portion of its length within its ends, of the solid platen form, as at 7c,beyond which, at each end, are the depressions or packets p p, surrounded by the lip q, the whole being integrally cast, and the intermediate solid platen portion 7a of the table is provided with the parallellongitudin al -T-grooves a, let in from its upper side and of any suitable, number, and as so far described the table is as usual in planer-tables. \Vithin the upper side of the solid platen portion 713 of the table, near each edge thereof, are longitudinally-extended gutters 17, and from the middle portion of one or both of said gutters 17 a lateral chute or gutter 50 extends to the edge of the table J, substantially as seen in Figs. 5 and 7, and from the middle portion of each of the T-grooves 'n a duct or passage 18 leads to the bottom of the platen, the said passages from the T-grooves being arranged with their outlets over the gutters 12 and intermediate pan 14:. vFrom the intermediate pan 14 and each of the side troughs. 12 12 pipes lead downwardly, under the lower ends of which a tank 20 is disposed. The said tank 20 at one top edge is provided with a spout 21, under which is located the opening 22 of another tank 23, and the table may, if desired, be provided with vertical holes 52, extending through it for securing the work upon the table.

The slide-block G, mounted on the slide-bar D, is provided with suitable journal-boxes 25 for the support and bearing of an emery or other suitable grinding-wheel 2 6, the extended shaft 27 of which at one side carries a pulley 28, to be independently driven through a belt 29 from an overhead shaft. Thegreater portion of the sides of said grinding-wheel and the whole of its periphery, excepta small arc thereof at its lower portion,is surrounded by a hoodor shell 30, suitably supported in a fixed position in relation to the slide-block G by brackets 31, there being a slight space between the inner walls of said hood and the outer surface of the grinding-wheel. There is entered at an intermediate portion of the height of said tank 23 the inlet-pipe t of a centrifugal pump 32, driven by a pulley 33, to the outlet-pipe 34 of which a flexible hose 35 is connected, which passes therefrom to or into proximity with the periphery of the grinding-wheel, being supported in any suitable manner, and there provided with a suitable stop-cock 36.

In the operation of the present machine with the work placed upon the table, with the SlldGsblOCk adjusted to present the grinding-wheel at and upon the upper surface thereof, and under the well-known driving mechanism, the table is reciprocated to carry the work to and fro under the rotating grinding-wheel, the slide-block being given an intermittent cross-feed, as usual. Water being pumped from the tank 23, through the hose 35, is directed upon the work and the periphery of the wheel, the hood 3O preventing any centrifugal throwing of same, and thence running onto the planer-table J, a portion of it flows directly into the T-slots a, and thence, through the passages 18, into the pan lat and troughs 12 of the bed, other portions thereof at the sides of the table running into the gutters 17, and where the side gutter 50 is provided at one or both sides of the table J. The water thence passes laterally into the side gutters 12 of the bed, and water within the side gutters 17 of the table which does not thus pass off laterally will be guided longitudinally into the end pockets 1), and thence into and through the T-grooves a and passages 18 to the said pan and gutters of the bed; and water may pass from the surface of the table, through the holes 52, into the intermediate pan and side gutters of the bed. The water, thence running through the pipes 19, is conveyed from said side gutters and pan to the tank 20, all sediment and particles of comminuted metal and emery, &c., being allowed to gravitate to the bottom of said tank 20, the clear portions thereof thence passing through the spout 21'at the upper edge of said tank, into the secondary tank 23, to be again forced to and upon the work, as before, and so on continuously as long as the grinding operation is continued.

In Figs. 1, 2, 3, and 4 is illustrated a novel construction of the abutment t on the slide to, against which the adjustable dogs m on the side of the table come in contact in their to-and-fro movement to secure the operation of the usual reversing mechanism by the movement of said slide 10. r is made in the form of an angular latch by one arm 38, pivoted, as at 39, in ear-pieces 44 of a stud 40, screwed into or otherwise attached to said slide 10, its other arm 41 being so formed as to project across and beyond the upper edge of said slide into the line of travel of said dogs at, increased rigidity thereto being given when the upper edge of the slide is notched or rabbeted, as at 42, into which the lower edge of the arm ll is allowed to rest, it of course being seen that this piv oted angular arm is capable of being quickly swung out of the line of travel of the said dogs, permitting the withdrawal of the table in either direction without changing the ad justment of the dogs, as desirable in many instances in the use of a planer.
